My 2016 Toyota Corolla suddenly showed a Check Engine light, and the dealer diagnosed a CVT transmission failure with code P2757. This code is linked directly to Toyota’s own TSB T-SB-0150-16 for torque converter clutch/valve-body failure. The dealer confirmed the issue and quoted me $11K to fix it. This is frightening because a failing transmission can slip, hesitate, or lose power at any moment, which puts me and others at risk. There were no early warning signs, just the sudden light. I brought it in immediately, and the problem was fully reproduced and documented by Toyota. My car is available for inspection whenever needed. Toyota corporate reviewed my case but offered very little help since my vehicle is just outside the 7-year timeframe for CA. I bought the extended warranty when the car was brand new. I have done every single service at Toyota, always on time, and my car has never been in an accident. I’ve taken care of it exactly the way Toyota told me to. This is not normal wear. This is a documented defect that puts drivers at risk and places an enormous financial burden on owners who did everything right. I’m filing this complaint because people deserve protection, accountability, and fairness, especially when a safety-related failure happens in a well-maintained vehicle. I’m only [XXX] , and I expected to own many more Toyotas throughout my life. My whole family drives Toyotas. I grew up believing this brand meant safety, reliability, and loyalty in both directions. I honestly wanted to be a Toyota driver for life. But facing an $11K repair for a known issue that Toyota already acknowledged in a TSB—without meaningful support—has broken my trust in a way I never expected.

Toyota has installed several parts on my 2016 corolla that were previous years' parts. In previous complaints, the tires (under 11,000 miles) started to dry rot. When filing the warranty repair, the dealerships and Toyota tried to claim that it was normal. After deep investigation, it was found that the tires were actually over a YEAR older than the release of the vehicle. The tire warranty started when they were sold to Toyota, not when the car was purchased. They did the same thing on Air intake components for the Air filter system for the car. This is the 3rd issue. Since I purchased the lease in 2016. The car constantly had a check engine light. Typically, it was suggested it was a "gas cap pressure check failure". But at all of the routine inspections and services. Dealerships never did anything but clear the code and keep going. I recently went back in to do a "smoke check" as I was getting tired of the code constantly pulling the check engine light. Now, supposedly, it's the Charcol canister. Ironically enough, Toyota had a recall on those items in 2015. I'm suspecting that this part if from that recall part, as it's been an issue (within service notes) to be checked since 2016 and was never suggested or further deep dive into the issue was never done. Now that the warranty is over, I'm supposed to pay another $800+ for the service parts and labor. Which Toyota should be liable for, as I KEPT taking the care to the dealership for warranty service, yet these checks were never done. When the service is underway, I would suggest sending this part to the federal safety agency to investigate the old recalled parts are in fact being installed on newer vehicles. As this would be the 3rd item that was from other older models that mysteriously appeared on my 2016 model corolla.

Car began with issues switching gears. It would hesitate to go into gear and once it was finally in gear it began to buck. Currently stationed overseas And brought my car to Toyota multiple times and was told they wouldn’t look at it since it’s an American spec Toyota and not a European. After a week of trying to get it fixed with no luck the vehicle began getting worse and wasn’t able to go above 35 miles an hour. Finally the check engine light came on. Brought it into a local mechanic and a P 2820 J code was the issue. After researching online I found that Toyota had a service campaign for the same issues I was having. The problem is with the ECU and the cars solenoid. Currently trying to get it repaired but Toyota will not help since I’m stationed overseas in europe and it’s an American Toyota. Toyota USA has been little to no help with the issue so I have had to stop driving the vehicle since it’s a safety hazard to my family.

I drove to toyota arlington for tire rotation on 2/4/21 and the car was running fine. Odometer was 44091 miles. After leaving the dealership, I drove about a mile then the engine lost power. The car could only go about 5 MPH. The car jerk up and down as if I drove on the rail road tracks. The check engine light, trac off and red steering wheel symbol lit up but not flashing. I went back to the dealer right away. I turned the car off, the attendant turned it back on. The check engine, track off and steering symbols were off. The code was not saved, so on 2/8/21 the independent shop could not duplicate the problem (44132 miles). On 2/12/21 the same symptoms came back at 44175 miles. This time the check engine light flashing, track off light and steering wheel symbols came on but not flashing. My wife turned the car off, waited for a few minutes then turned it on. The check engine light was off but the trac off light remained on. In the past, after I turned the car off and turned it on one click, the symbols were on, and when the ignition turned on, the symbols were off. This is a safety issue. The car also smell like a burning tire. We were driving about 35 MPH on lane number 1 (next to yellow lines median) on a county 4 lanes highway. The car slowed down to about 5 MPH, jerk up and down and the car vibrates and it happened twice in a week. The car is only 4.5 years old and only 44175 miles. The second independent shop read the code as p0301, misfired. He suggested to bring the car to the dealer for toyota to fix it under powertrain warranty. No repair has been done yet.

Trac off, check engine, and maintenance required lights suddenly appeared while the corolla was being driven on a state road. The car had just passed its 20,000 warranty check with no problems. I was on the way to a regularly scheduled oncology appointment. I had to cancel the appointment and drive the car to the dealer. Technicians determined a rodent had chewed through the transmission control harness. This problem is not covered by any toyota warranty. So far, I've been forced to spend nearly $1,000 on rodent-related repairs. I have stage iv cancer. I bought this car expressly to have reliable transportation to cancer treatments, most of which are out of state. I can't afford these rat-related repairs. Letters and phone calls to toyota have proved futile and frustrating. The rats are considered by the corporation as an outside source, and therefore, not covered by any warranty. The "outside source" is the soy that was stupidly used to make the insulation protecting the engine's electrical wiring, crisscrossing the engine. I had a 1991 toyota that I parked in the same unprotected, driveway spot for nearly 25 years where the newer corolla is now parked. There were no rodent issues whatsoever. Same for a 1991 jeep wrangler. Ditto a 1997 buick lasabre. The only car being eaten by mice and rats is the newest car--the 2016 corolla with soy-based wiring. Soy is a food source. I know. I grew up on a farm and we fed it to our cows as a protein source. I need a reliable, economical car to get to lifesaving cancer treatments. This car isn't it. Toyota could care less. For that, the company needs to be held accountable. They are risking the lives of everyone who owns one of these rat trap cars. So far, toyota has absolved themselves of all responsibility for this inherent and dangerous manufacturing defect. I can't fight stage iv breast cancer and toyota. Thank you.
